Hibiscus Leaves Turning Yellow

Question

My hibiscus is in a planter and is starting to bloom, but the leaves are turning yellow and they are very sparse too. My gardenia plant is also turning yellow. Am I watering too much or too little?

Answer 1

It could be either. Water only when the soil is dry to the touch on top, but don't wait until the soil is dry below that. Also, make sure to give them fertilizer, as a lack of fertilizer can also cause yellow leaves.
